Topological Gap Opening without Symmetry Breaking from Dynamical Quantum Correlations
Francesca Paoletti, Laura Fanfarillo, Massimo Capone +1
Topological phase transitions are typically associated with the formation of gapless states. Spontaneous symmetry breaking can lead to a gap opening thereby obliterating the topolo…
Nematic spectral signatures of the Hund's metal
Laura Fanfarillo, Angelo Valli, Massimo Capone
We show, by means of dynamical mean-field theory calculations, that the experimental fingerprints of the nematic order in iron-based superconductors are intrinsically connected wit…
Non-local correlations in Iron Pnictides and Chalcogenides
Shinibali Bhattacharyya, Kristofer Björnson, Karim Zantout +6
Deviations of low-energy electronic structure of iron-based superconductors from density functional theory predictions have been parametrized in terms of band- and orbital-dependen…
Photoinduced nematic state in FeSeTe
Laura Fanfarillo, Damir Kopić, Andrea Sterzi +8
FeSeTe compounds present a complex phase diagram, ranging from the nematicity of FeSe to the magnetism of FeTe. We focus on FeSeTe, where the…
Charge disproportionation, mixed valence, and Janus effect in multiorbital systems: A tale of two insulators
Aldo Isidori, Maja Berovic, Laura Fanfarillo +3
Multiorbital Hubbard models host strongly correlated 'Hund's metals' even for interactions much stronger than the bandwidth. We characterize this interaction-resilient metal as a m…
Ultrafast orbital manipulation and Mott physics in multi-band correlated materials
Andrea Ronchi, Paolo Franceschini, Laura Fanfarillo +12
Multiorbital correlated materials are often on the verge of multiple electronic phases (metallic, insulating, super- conducting, charge and orbitally ordered), which can be explore…
Orbital-dependent Fermi Surface shrinking as a fingerprint of nematicity in FeSe
Laura Fanfarillo, Joseph Mansart, Pierre Toulemonde +6
The large anisotropy in the electronic properties across a structural transition in several correlated systems has been identified as the key manifestation of electronic nematic or…
Unconventional Hall effect in pnictides from interband interactions
L. Fanfarillo, E. Cappelluti, C. Castellani +1
We calculate the Hall transport in a multiband systems with a dominant interband interaction between carriers having electron and hole character. We show that this situation gives…
